` BUMPER.

Application filed September 27, 1928. Serial No. 308,717.

This invention relates to bumpers, and has for its purpose the provision oi: a bumper composed ot a i'ew parts and those parts united in such a way as to securely hold them against displacement and movement in regard to each other.

It is the object of this invention to pro vide a bumper in which there are essentially one back bar and two parallely spaced front bumper bars united to eachother and to the back bar in firm and secure gripping relation.

It is also a purpose of this invention to provide a bumper in which the back bar is united to the impact bars in a secure manner, but withoutany direct gripping relation between the two `parts otherthan that ot friction. The holding of the parts together is accomplished by plates which securely grip ythe parts and hold them in f relation to each other.

For the purpose of illustration there is shown in the accompanying drawings a preferred embodiment of this device, which is used only toi-the illust-ration.

In the drawings:

Figure 1 is a top plan View of the bumper in condition to be attached to an automobile.

Figure 2 is an enlarged View of one end ot the bumper, as shown in Figure 1.

Figure 3 is a face viewy et' the parts shown in Figure 2. f

Fi gure l lis a cross section on the line 1l-1 olE Figure 3.

Figure 5 is a cross section on the. line 5*-5 ot Figure 2.

The bumper is shown as a whole in Figure 1, and is composed essentially of two parallel arranged bumper bars, each oi' which is indicated by the numeral 1. These bars are curved backward at the end, as indicated by the numeral 2. For the purpose of holding these bars in relation to each other and 'for the purpose et attachment to an automobile there is provided a back bar 3, which has each end thereof looped, as indicated by the numeral 1. f

The ends of the back bar are attached to the impact bars by means of plates and rivets. The plate is indicated by the numeral 5, and has on each end thereo a stud 6. This stud is elongated and extends across the plate, and is adapted to engage a hole in either of the front bars. This hele is elongated to suicient size to receive the elongated stud 6.

At the central part of the plate 5 there is a stud 8, which extends substantially across the plate and is adapted to engage between the front bars and hold them in spaced relation to each other when the studs 6 are in engagement with the holes7. The stud 8 has a round projection from the center thereof, which is adapted to iit within a correspondingly shaped hole in the back bar 3. This round projection on the stud 8 is indicated by the numeral 9 and iits in the correspondingly shaped hole in the bar 3.

For the purpose of holding the back bar rassembled to the 'front bars and to the plate 5 the end of the rounded part 9 is 'formed into a head 11 by riveting. these parts are firmly held together.

The bars 1 are prevented from moving apart by means oli the studs 6, and are also held in contact with the back bar 3 by means of the rivet orstud 9. At each end ot' the y Yfront bars 1 there is a plate 12, which has .formed thereon at each end an elongated stud 13. These studs 13 fit within holes 14 formed near theinner edges of the ront bars 1.

Projecting from the central 'part of the plate 1Q isfan elongated stud 15 -adapted to tit between 'the ends of the front bars to hold them in spaced relation. This stud 15 is extended in a round end part 1G, which is adapted to lit within a similarly shaped hole 17 in a forging or casing 18.

Then the parts are assembled as shown in Figure 5y with the studs 13 within. the holes 14 and the stud lbetween the ends of bars 1, and the 'forging or casing 18 securely united thereto by means of the round extension of the stud 15, which is riveted as indicated by the immoral 19, the

yparts are securelyheld in lixcd relation to each other. i

By this vmeans The forging 1S has on each side thereof a the end of the bars and prevent its rotation,

there are formed en ythe casing 18 two ears 22. These ears extend between the bars in line with the stud 15.

On account of the studs 8, 15, 7 and 13 being elongated and fitting within similarly shaped holes the front bars, when thus united, are held in a way that thereV is very llitt-le longitudinal motion ot one to the other, due t-o the length of these studs, which prevents any tendency to rotate one with respect to the other. That is, in other words, the plates 5 and 12 are held against tilting motion in relation to the front bars.

It will be observed that there is no direct connection of the back bar to the front bars.

rllhe only means of connecting the bars 'to- Uether is through the )lates and the studs D .C

thereon. The front plates are connected to the front bars by means of studs and holes.

and a spacing stud between the plates. The plates 5 aie connected to the back bar by means of a rigid connection with the central stud which passes through the hole in the back bar.

F rom observation it will be seen that the parts have nothing more than a frictional Contact with each other, and are held in engagement with each other by means ofthe plates. These plates being constructed as they are, and being firmly riveted to the back bar, hold the parts in position with relation to each other so as to prevent movement of one with respect to the other.

It is also yto be noticed from an observation of Figures 4 and 5 that the central plates only Contact with the edge of the middle of the front bars,fand do not overlap the holes in the front bars, While from Figure it will be seen that the. end plates having their studs near the inner margin of the front bars, the member 18 extends over the holes in the front bars and entirely protects the stud 13.

I desire to comprehend within my invention such modifications as may be clearly embraced within my claims and the scope of my invention. r

Having thus Vfully described my invention, what I claim as new and desiretol secure by Letters Patent, is:

`1. In a bumper, a. pair of bumper bars, each having a hole in one end thereof, a plate having studs thereon to engage said holes and a stud fitting between said bars, a casing adapted to receive the last named st-ud,Y said stud having its end riveted against saidcasing to hold the bars 'in relationto each other.

2. In a. bumper, a pair efbumper bars held in spaced parallel relation to each other, a plate engaging one side of said bars at the ends thereof, and a casing engaging the other side of said bars, said plate and casing cooperating with each other and the bars to hold the bars against movementwith relation to each other to protect the end of the bumper.

3. In a bumper, a pair of bumper bars arranged in spaced parallel relation to each other, each bar having a hole remote from the end thereof, a plate having studs thereon in engagement with said holes and a stud extending between said bars and engaging the edges thereof, and a back bar having a hole in an end thereof, said back bar engaging said pair of bars across the space therebetween with the last named stud in said end hole, and riveted so that the back bar is held to said plate and the bumper bars.

means to hold said bars in spaced parallel relation to each other, said means including a casing having end and side flanges to give rigidity to the end of the bumper and ears fitting kbetween the bars, and a plate cooperating with the casing to grip and firmly hold the bars.

G. In a bumper, a pair of bumper bars arranged in spaced parallel relation to each other, each bar having a hole'near each end thereof, plates having studs in engagement with said holes, studs on said plates extending between said bars and engaging the edges thereof, a back bar having a hole in each end thereof, said back bar engaging said pair of bars across the space therebetween with the last named stud in said hole, and riveted so that the back bar is held to said plate and bumper bars.

7. In a bumper, a pair of bumper bars, each bar having an oblong hole therein, a backr bar having a hole therein and in engaoement with said pair of bars, and a plate having lugs thereon to lit in said holes and a lug to tit between said pair of bars and engage the edges thereof, the end of 'said last named lug being in the hole in the back bar and riveted thereto to hold the bars in relation to each other.

In testimony whereof, I `affix my signature.

EDWARD H. MGGLOUD.
